genesis and evolution

2. HCI has the potential to change human behaviour
HCI is transdisciplinar
HCI emphasizes human values and goals
HCI is vast
Usability is a key issue in HCI
HCI enables the extension of human capabilities
HCI is a gap filler
HCI is good in predicting the future, Alan Kay way
HCI is about finding the perfect symbiosis between users and computer
application
HCI more than just concerned in the design of personal computer and it’s
operating system
HCI serves as a bridge between science and practice
HCI build on human factors and cognitive sciences

4. Electrical Symbolical Textual Graphical Tangible
Paul Dourish
First analog
computers where
operations were
directly encoded in
it’s circuits which
needed to be
configured for each
new task.
There were no
“users”, only
programmers.
First assembly
languages appeared,
that rendered
machine level
instructions into
symbolic
expressions.
The actual interaction
took still place with
encoded punch
cards, although the
languages could
already be
considered textual.
With the appearance
of teletype machines
and video terminals,
the primary form of
interaction became
textual.
This can be
considered the origin
of interactive
computing -
“interactive loop” in
which the interaction
became an endless
back and forth loop
of instruction and
response between
user and system.
With the appearance
of graphical UIs the
interaction moved
from the one
dimensional stream
of characters to a
two dimensional
space.
The task of
managing
interaction became
the task of
managing space.
Interaction directly
through physical
artifacts rather than
graphical interfaces
or classical input
devices

5. focus on the properties
of specific system
components
focus on tasks at
hand
focus on socially and materially
embedded interactions

Rigid guidelines.
Formal methods.
Systematic testing.
Focus on context and groups
working with a collection of
applications.
Theories: situated action,
distributed cognition and
activity theory.
Proactive methods: variety of
participatory design
workshops, prototyping and
contextual inquiry, qualitative
approaches studying use as it
happens.
Use of context and application types
are broadened. Computers are
increasingly being used in private
and public spheres. Technology
spreads from workplace to homes
and everyday lives and culture.
Theoretical focus on aesthetics,
cultural level, cognitive expands into
emotional, cultural, historical focus
on experience.
Methods moved away from
commitment to users towards more
exploratory take-it-or-leave it
approach where designers seek
inspiration from use.
